　　Choosing an Occupation

　　One of the most important problems a young person faces is deciding what to do. There are some people, of course, who from the time they are six years old "know" that they want to be doctors or pilots or fire fighters, but the majority of us do not get around to making a decision about an occupation or career until somebody or something forces us to face the problem.

　　Choosing an occupation takes time, and there are a lot of things you have to think about as you try to decide what you would like to do. You may find that you will have to take special courses to qualify for a particular kind of work, or you may find out that you will need to get actual work experience to gain enough knowledge to qualify for a particular job.

　　Fortunately, there are a lot of people you can turn to for advice and help in making your decision. At most schools, there are teachers who are professionally qualified to give you detailed information about job qualifications. And you can talk over your ideas with family members and friends who are always ready to listen and to offer suggestions.

　　2.【解析】[N]該句句意為:巨壩和灌溉工程的建設(shè)好處多于壞處。解題依據(jù)為本文第三段第二句話But many countries continue to build massive dams and irrigation systems, even though such projects can create more problems than they fix. (雖然產(chǎn)生更多問題，許多國家仍繼續(xù)建巨壩和灌溉工程。)由此可知，壞處多于好處，所以該題與原文之義不合。

　　6.【解析】[N]該句句意為:美國人將不會面臨缺水問題。該題解題依據(jù)為文章第七段第二句話 But Americans could face serious water shortages, too, especially in areas that rely on groundwater, 顯然本題之意與原文之義不合。
